Abstract

A transmitting apparatus includes an apparatus main body, and a plug-in unit, wherein the apparatus main body includes a holding member that holds a cooling plate displaceably in an upward-downward direction in the slot of the apparatus main body, and the plug-in unit includes a casing allowed to be inserted and removed into and from the slot of the apparatus main body, a substrate that is housed in the casing and on which a heat generating, component is mounted, and a displacing member that displaces the cooling plate held by the holding member to a position at which the cooling plate gets contact with the heat generating component or a position at which the cooling plate gets contact with a heat transfer member disposed on the heat generating component in conjunction with operation of inserting the casing into the slot of the apparatus main body.

Claims

1. A transmitting apparatus comprising:

an apparatus main body in which a slot is formed; and

,

a plug-in unit configured to be inserted into the slot of the apparatus main body, wherein

the apparatus main body includes

a holding member that holds a cooling plate displaceably in an upward-downward direction in the slot of the apparatus main body, and

the plug-in unit includes

a casing allowed to be inserted and removed into and from the slot of the apparatus main body,

a substrate that is housed in the casing and on which a heat generating component is mounted, and

a displacing member that displaces the cooling plate held by the holding member to a position at which the cooling plate gets contact with the heat generating component or a position at which the cooling plate gets contact with a heat transfer member disposed on the heat generating component in conjunction with operation of inserting the casing into the slot of the apparatus main body.

2. The transmitting apparatus according to claim 1, wherein

the apparatus main body further includes a first electrical connector,

the plug-in unit further includes a second electrical connector that is mounted on the substrate and is coupled to the first electrical connector of the apparatus main body in a state in which the casing is inserted in the slot of the apparatus main body,

the holding member holds the cooling plate at a position higher than the first electrical connector and the second electrical connector in the slot of the apparatus main body, and

the displacing member displaces the cooling plate held by the holding member from the position higher than the first electrical connector and the second electrical connector to the position at which the cooling plate gets contact with the heat generating component or the position at which the cooling plate gets contact with the heat transfer member in conjunction with the operation of inserting the casing.

3. The transmitting apparatus according to claim 1, wherein

the holding member is a plate spring, and

the displacing member is a plate spring and displaces the cooling plate held by the holding member to the position at which the cooling plate gets contact with the heat generating component or the position at which the cooling plate gets contact with the heat transfer member by elastically pressing the cooling plate in a direction toward the heat generating component in conjunction with the operation of inserting the casing.

4. The transmitting apparatus according to claim 1, wherein

the plug-in unit further includes a lever that is pivotally disposed on the casing and is operated to pivot in the operation of inserting the casing,

the holding member is a plate spring, and

the displacing member is a block in which an inclined surface is formed at an end part, is linked to the lever with intermediary of a linking member, and displaces the cooling plate to the position at which the cooling plate gets contact with the heat generating component or the position at which the cooling plate gets contact with the heat transfer member by moving in such a direction as to get closer to the cooling plate held by the holding member and guiding the cooling plate along the inclined surface in conjunction with pivoting of the lever.

6. The transmitting apparatus according to claim 1, wherein

the holding member is an expanding-contracting mechanism capable of expanding and contracting in the upward-downward direction by rotation of a pinion gear and includes a lower surface to which the cooling plate is fixed, and

the displacing member is a rack gear and, in conjunction with the operation of inserting the casing, engages with the pinion gear of the holding member and displaces the cooling plate to the position at which the cooling plate gets contact with the heat generating component or the position at which the cooling plate gets contact with the heat transfer member by rotating the pinion gear and expanding the holding member in a direction toward the heat generating component.

5. The transmitting apparatus according to wherein

the holding member is a pinion gear, includes a rotating shaft part in which screw grooves are formed in a side surface, and holds the cooling plate through engagement of the rotating shaft part with a screw hole formed in the cooling plate, and

the displacing member is a rack gear and, in conjunction with the operation of inserting the casing, engages with the holding member and displaces the cooling plate to the position at which the cooling plate gets contact with the heat generating component or the position at which the cooling plate gets contact with the heat transfer member by rotating the holding member and moving the cooling plate in a direction toward the heat generating component along the rotating shaft part.

7. A plug-in unit inserted into a slot of an apparatus main body in which the slot is formed and that includes a holding member that holds a cooling plate displaceably in an upward-downward direction in the slot, the plug-in unit comprising:

a casing configured tube allowed to be inserted and removed into and from the slot of the apparatus main body;

a substrate configured to be housed in the casing and on which a heat generating component is mounted; and

a displacing member configured to displace the cooling plate held by the holding member to a position at which the cooling plate gets contact with the heat generating component or a position at which the cooling plate gets contact with a heat transfer member disposed on the heat generating component in conjunction with operation of inserting the casing into the slot of the apparatus main body.

8. The plug-in unit according to claim 7, wherein

the holding member is a plate spring, and

the displacing member is a plate spring and displaces the cooling plate to the position at which the cooling plate gets contact with the heat generating component or the position at which the cooling plate gets contact with the heat transfer member by elastically pressing the cooling plate held by the holding member in a direction toward the heat generating component in conjunction with the operation of inserting the casing.
